Description

3.5mm audio plug

Technical Field

The utility model relates to an earphone plug technical field especially relates to a 3.5mm audio frequency plug.

Background

The 3.5mm analog audio interface is the most traditional and most common analog audio interface, and has the advantages of simple structure, convenient use and low cost. Almost all devices such as mobile phones, game machines, audio players, earphones and the like have the interface, so that 3.5mm audio lines are still produced and applied in large quantities.

A conventional 3.5mm audio line is a 4-segment plug, and the signal definitions (counted in order from the small end) are, in order: left channel, right channel, ground, microphone signals. The user can plug the audio plug into a playing device such as a mobile phone, MP3/MP4/MP5 and a device with a 3.5mm audio jack, and listen music and talk by using a microphone.

However, conventional 3.5 audio plugs of this type are only designed on the market with one common ground, namely the microphone ground and the loudspeaker audio ground. This results in mutual crosstalk. Especially microphone signals are often subject to crosstalk by the loudspeaker signal. For example, when a user listens to music through an earphone with a 3.5mm plug, the sound of the earphone speaker of the user often interferes with the microphone circuit (especially when the volume of the speaker is large), so that the microphone circuit collects a speaker signal and transmits the speaker signal to another party in a call, and poor use experience is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a 3.5mm audio plug aims at solving prior art, controls the sound channel and crosstalks to microphone circuit through the ground wire and leads to microphone circuit to collect loudspeaker signal transmission and give the other party of conversation, has caused the problem that not good use was experienced.

The embodiment of the utility model provides a 3.5mm audio plug, including the plug body with set gradually in microphone section, microphone grounding segment, loudspeaker grounding segment, right track section and left track section on the plug body.

The utility model discloses separately set up microphone and the ground segment of controlling the sound channel, avoided controlling the sound channel and crosstalking to microphone circuit through the ground wire and leading to microphone circuit to collect loudspeaker signal transmission and give the other party of conversation, also can avoid hearing the sound of oneself moreover, improve experience.

Wherein, the utility model provides an audio plug's shape and size still are original specification, only with the microphone originally with control the sharing earthing section of sound channel and fall into two parts-microphone earthing section and loudspeaker earthing section, make the utility model provides an audio plug still is applicable to current female first socket, need not to redesign female first socket.
